Application filed October 22, 1921. Serial No. 509,515.

T 0 all whom it may concern:

Be it known that 1,-WALTER EMILE FISHER,

a citizen of the United States, and a resident of New Iberia, in the parish of Iberia and State of Louisiana, have invented certain new and useful Improvements in Oil-Burning Apparatus, of which the following is a specification.

My invention relates to oil burning apparatus particularly designed for use in conjunction with steam boilers, and a purpose of my invention is the provision of an oil burning apparatus by means of which the intensity of the flame emanating from the burner is automatically controlled in accordance withthe variance in pressure of steam in the boiler and in such manner. that the relative proportions of oil and steam applied to the burner remain constant.

It is also a purpose of my invention to provide an apparatus including a burner constructed to utilize the steam in effecting a super-heating of the oil within the burner whereby a far more efficient combustible mixture is secured.

I will describe one form of oil burning apparatus embodying my invention, and will then point out the novel features thereof in claims. v

In the accompanying drawings:

Figure 1 is a view showing in vertical section one form of apparatus embodying my invention. I

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

Referring specifically to the drawings, in which similar reference characters refer to similar parts, my invention in its present embodiment comprises a cylindrical casing designated generally at K and including sections 15 and 16 each of which is of semi-cylindrical form. These sections are secured together by means of rods or bolts 17, the sec tion 15 being formed upon its inner side with cylindrical projections 18 arranged adj acent the opposite ends of the section with the projections spaced apart in parallelism and rigidly supported by flanges 19 formed on the section 16. Each projection is divided transversely by means of a 20 into two chambers. The chambers in the upper projection are designated at S and D, respectively, and are adapted to communicate with each other through the medium of a port 21 formed in the partition 20 and controlled by a valve V. The chambers in the lower projection are designated at S and D, respectively, and are likewise in communication with each other through the medium of the port 22 formed in the par tition 20 and controlled by a valve V.

The chamber S constitutes an oil supply chamber to which oil is adapted to be supplied by a pipe P connected to an oil reservoir. The chamber S constitutes a steam supply chamber to which steam is applied through a pipe P connected to a boiler (not shown) for which the oil burning apparatus is designed. The chambers D and D constitute oil and steamdispensing chambers, respectively, the passage of oil and steam to these chambers being controlled through the medium of the valves Vand V. ,As clearly shown in Figure 1, the seat for the valve V is disposed reversely with respect to the seat for the valve V, the two valves working upon opposite sides of the partitions 20 and fixed to the ends of stems or rods'R and B, respectively, slidably mounted through stuffing boxes 23. To effect simultaneous opening and closing of the valves V and V, a lever L is provided which is fulcrumed at a point medial of its ends as indicated at 24 on the end of a. standard 25 bolted to the casing K. This lever is provided at its ends with slots 26 in which work pins 27 fixed to the rods R and B. This arrangement effects the forward move ment of the valve V and the rearward movement of the valve V when the lever L is rocked in one direction and a reverse movement of the valves when the lever is rocked in the other direction. Actuation of the lever is effected through the medium of the rod R which is continued to constitute the rod of a piston 28 mounted in a cylinder 29 sustained on a suitable base 30. Steam is supplied to the cylinder 29 through a pi e 31 whichis adapted tobe connected to the boiler mentioned, and under the ac 7 tion of the steam the piston is moved to the right as when viewed in Figure 1. This piston is normally urged to a pointmedial in the present instance is made up of two of tho endsotf the piston by means of a coiled expansible spring 32 embracing the piston rod within the cylinder as clearly shown.

The oil burning apparatus includes burner'designated generally at B and which like sections 33 and '34 provided with flanges at their confronting, edges through which bolts 35 extend for securing the sections together 1n the form of a rectangle as clear.

ly shown in Figure2. As shown in Figure l. the outlet end of the burner. is formed with'oppositelyinclined walls, the confronts ingedges of which are arranged in spaced relation to provide an outlet port 36. Secured-to the flanges and between the sec- 1 tions of theb-urner is a dividing paititiony 3T-pr'efe'rablyformed on copper and arranged to divide the-burner-into 'anu-pperand'oil chamber 38 and alower and steam "chamber 39; These chambers are at all times ,in' communication with thed1spens4 ingchambers D and D respectively,

throughfthe medi'umpf pipes 40 and 41',

respectively. i In the operation of'the apparatus, the burner-"=13 is adapted to be arrangedwithin the firebox ofa boiler, with the pipe 81 con-, nected to the 'boiler to supply steam" to the cylinder 29 as previously described. /Vith no steam pressure in the boiler, the piston occupies. the medial position shownunder the. action of the springv 32, and in this po-' sition the valves V and V. are in full open position'se as to allow the maximum supply of oil and steam tothe burner 13, the oil and steanr passing. froin-the supply chambers, S and S through the ports 21 and 22 into I the dispensing chambers 11 and D and:

thencethroughthe pipes 40 ail'dfll into the chambers 38 and 39. The oil and steam leave the. burnerthrough the port. 36, an intermixing of the two occurring at the forward end of the partition 37. As the steam traverses the chamber 39the partition g'fllwhich is preferably formed of copper, becomes intensely heated so that as the oilis introduced into the upper chamber 38 it falls on the partition and is thus vaporized so that it finally leaves the burner in the form of 'a vapor and in combining with they I steam ,produc'es ajhighly, efiieient combuse I tilole fmixture.

. in the boiler increases. it, ofnecessitypin As. the pressure of steam creases the pressure in the cylinder 29 thus moving the piston 28 to the rightagainst the. tension of the spring 32. Under this action the rodR is moved forwardly so as to close the valved?" and as the lever L is operatively connectedto the rod B, it isv evident ,that 'tl1ej a1va Vj will likewise be moved't'o closed position. Byyirtue' of the;

valve operating mechanism the degree of movement of the two valves is the same so that as the supply of oil to the burner is decreased the supply of steam is decreased in the same proportion thus maintaining at all tunes a proper mixture of oil and steam.

Should the pressure of steam' i'n theboiler decrease it will be clear that the reverse operation takes place so as to move the valves to open. position and thus increase the supply of oil and steam to the burner. Although I have herein shown and described only vone form of oil burning apparatus embodying iny'invention, it is'to be .understood that various changes and modi-i.
